ROOF-FLASHING HOLDER.

Application filed June 21,

This invention relates to new and useful improvements in flashing holders for roofs and the like, and the object of the invention is to provide a very simple type of holder which will be easily held in place during erection of the building and which when in position will be highly eilicient in operation.

Another object is to provide a flashing holder of simple construction for use in the construction of concrete buildings.

In my invention, I provide a flashing holder made of a single piece of material bent to form a receiving channel for the upper edge of the flashing. Part of the material extends beyond the face of the wall, said part being adapted to form a lock for the flashing to hold it in position against the face of the wall. The lower part of the flashing holder lies against the face of the 0 wall and the lower edge of this part is bent upwardly and engages with the material in the wall to lock the holder in position. Reinforcing bars or channels may be provided between the upwardly bent lower edge of the T5 holder and an upwardly turned portion of the guide. Provision is also made for nailing the holder to the wall forms during the course of erection so that on removal of the forms, the holding nails may be easily 159 withdrawn. Lugs are formed in the holder and are bent inwardly to form a gripping means engaging with the material in the wall to prevent movement of the holder. Means are also provided at. the back of the holder to ensure that no water will pass into the wall between the uppermost face of the holder and the adjacent portions of the wall.

In the drawings which illustrate one form of my invention Figure 1 is a sectional side elevation of a wall with the flashing holder mounted therein and showing the manner of positioning the flashing during the course of erection of the wall.

Referring more particularly to the draw ings, l1 designates a concrete wall which is built in the manner well known in this art, by pouring concrete in its plastic state into forms and then allowing the concrete to set before withdrawing the forms. My improved flashing holder has been designed to suit concrete wall construction and to simplify to a great extent the cost of securing a holder of this class to the wall while it is under construction.

The flashing insert or holder 12 is made from a single sheet of metal, part 13 of which is adapted to align with the face 14 of the wall. Extending at substantially right angles to the part 13 is the guide 15 between the parallel faces 16 of which the upper edge of the flashing 17 is placed. The closed end 18 of the guide consists of two thicknesses of the metal sheet pressed closely together and bent upwardly at an angle to the guide or to the two spaced parallel portions of the sheet forming the guide. The free edge 19 of the uppermost portion of the guide extends beyond the face 14 of the wall and is adapted when bent to lie parallel to said face to act as a locking means for holding the edge of the flashing within the guide.

The lowermost edge 20 of the holder is bent upwardly and inwardly from the face of the wall and also to the portion 13 to form a means for securing the flashing holder to the wall. Extending from the underside of the guide to the inner face of the portion 13, are the channel-shaped reinforcing members 21, the webs 22 of which extend upwardly and over the closed ends of the guide and may be secured thereto by soldering or such like means. The webs may be also soldered to the lower upwardly turned edge of the holder. In Figure 9 I have shown a slightly different method of attaching the reinforcing channels to the holder without the necessity of soldering same. InjFigure 9, the webs 2 2* of the einforcing means pass tnreegn slots 85,-

i a do formed in the underside of the closed upwardly turned end or the euide and hetween the adjacent faces of said end and then through a slot at the point 37, Where the metal :t-orining;- ie guide is doubled over. The Webs after passing through the slot 86 are bent over to lie flat against either outer surface of the closed end of the guide. but preferably against the surface 38.. in Figure 9, the Web 22 passes through a s ot 39 formed in the upwardly turned edge of the holder and is then folded or doubled over to contact with the outer surface of said edge il. The flanges oil? the channels are bevelled at their ends and to lie parallel and in contact with the guideand the innermost face of the portion 13 of the t to preventdeli holder, and act as a strut orination of the holder during the course of erection of: the Wall or during transpon tation of said. holders. lhe reinforcing members are spaced at intervals in the ion gitudinal direction of the holders to keep same in shape and to form an attaching means for securing the holders to the Wall Punched from the portion 13 ot the holders are the dovetailed lugs which extend into the Wall to form a .li'urther Wall attaching; means for the holder.

The following is a detail Oil: the method of erecting a concrete Wall having my iniproyed flashing insertor holder securcd The form. for the lace 1 5i; ot the thereto. portion of the Willi shown, is built in sec tions 26, 2 and 28 the section. 27 extending out *ardly from the faces of the other sec-- tions. In the preferred type of form, sec tion 27 is nailed to the top of section 26 and is made of a thickness equal to the space between the parallel surfaces of the flashing holder to hold said guidein position and to keep same from collapsing during the course ol pouring the plastic concrete between the ZEOHUS; The flashing holder is nailed to the face of section 2-6, the nails 28 passing; through apertures 29 formed in depressions SO in the portion 13 of the holder and preferably between the dovetailed lugs. The depressions are positioned near the guides and away from the face of section 26. The depressions are of circular form and to strengthen the portion '13 grooves Sl are formed in. the face of the portion 13, each of said grooves coininunieating at its upper end with a circular depression and extending downwardly there from to a point in proximity to thelowermost edge oil the holder. The holder is now in position between the forms and is held from movement by nails 28 The forms are now ready for receivingthe plastic concrete that is the flashing holder is secured to section 26, section 2? is secured to the upper end olsection 26' to hold the parallel.

portions ot'the guide apart, and to hold the eases? tree edge of the holder in posiliom while section 28 is mounted above the tree edge of the holder. The concrete is then poured in its plastic state between the terms, only one ol which. is shown in the drawing, the other "l'orn'i being spaced lll'lOl'tBflOl'll a dis lance ecpial to the thickness oi? the Wall under construction. The concrete lows around the t..'einliorcin :r inen'ihers, around the h p and the guide and also the bottom edge of the holder so that when the concrete is set the holder Will be secured to the wall. it will be noticed that the section holds the spaced sides oi the guide apart and prevents buckling: of same during the forming of the trail. l l hen the concrete is set, the forms are dismantled and pulling: section 26, nails 28 are pulled With it as radially disposed cuts or wealrened portions extend outwardly from the nail apertures to allow the head of the nail to pull clear oi? the holder. The depressions and grooves great ly strengthen the hold. r in p: iiiinity to the nail apertures and prevent distortion of the holder at this point due to the pulling out of the nails. The holders may be made in long lengths reinforced at intervals; or they may he used in the manner shown in Fieure 6, that is in short lengths with the upperinost holder spaced from but in overlap ping relationship at one end to the holder immediately below it. l l hen used in long lengths the ends 42 of the dashing holder may he cut as shown in Figure 8,. that is the corner of the closed end oi the guide may be so cut that the adjacent edges of two sections of flashing" holders may lie in overlapping engagement to "form a water tight joint in the simplest and most ellicient manner.

Many modifications may he made to the device, Without departing from the spirit of the invention,

The flashing is then placed in the guide and the free end of the holder bent over said flashing to hold it securely in position. It will be seen that a flashing" holder built in the manner herein described greatly facilitates the attachment of flashing to concrete walls, roots and the like. It is simple to construct, and manufacture, and when in position forms a protection for joints between the Wall and any horizontally or tapered member adjoining said Wall,

Having thus describediny invention, What I claim is;-

1. in Wall construction a flashing holder having); a channel guide for the reception of one edge of the flashing. said. holder having a portion aligning with the face of the Wall depressions formed in the last mentioned portion, and means formed in the depressions to allow the flashing: to be secured by nails to the torn'is durii the construction oi the wall, and means formed in the last till LOO
